An insulated conductor heater may include an electrical conductor that produces heat when an electrical current is provided to the electrical conductor. A radial bearing and a one-way clutch are disposed axially adjacent to each other between the boss of the side-cover and the turbine shaft. A further metal foil current collector extends from a longitudinal edge of the anode sheet. The cup assembly includes an outer cup and an inner cup, where the outer and the inner cups are joined with a living hinge such that the inner cup is able to be rotated from a side-by-side position with the outer cup, to a position within the outer cup.
